Rainham: your questions answered
Is air conditioning in Rainham permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Central Rainham is a short walk from the Rainham Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at Havering council, normally the authority for Rainham.
Do I need permission to put air conditioning in my flat in Rainham?
Typically, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Will you need to do electrical work?
Most systems need their own supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and we are NICEIC approved, so we can install and certify it.
Can the outdoor unit go on a roof or at ground level?
Wall brackets, ground level and flat roofs are all options, wherever the pipe route, airflow and servicing access work best. Noise near bedrooms and boundaries is part of the decision and position can affect planning.
How much is air conditioning for one room?
Single-room systems start from £1,200 + VAT and are typically up to £2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork, and we fix it after a survey or from your photos.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and we hold it.
How we handle air conditioning in Rainham
Air conditioning isn’t only for summer: most modern splits heat too. The Energy Saving Trust recognises that air-to-air heat pumps often go by the name air conditioning, so a well-chosen unit can be useful in winter as well as summer. For air conditioning in Rainham, you get one team and one number from survey to sign-off, wherever you are in Greater London.
In a London area like Rainham, many of the homes we are asked about are flats, maisonettes and terraced houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. A freeholder or managing agent often has a say in a flat, so we write up the proposed positions for them to see.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Owner checks or an engineer?
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring 07833 053749 or drop us a line.
Air conditioning around Rainham
Valuation Office Agency council tax records show about 47% of homes across Rainham and its surrounding area date from 1919 to 1939, and about 37% of households live in terraced houses, according to Census 2021 figures. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. With a terrace, the back wall or an extension roof is usually the best place for the outdoor unit. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.

How the job changes from property to property
Multi-split systems
A multi-split runs several indoor units from one outdoor unit. It saves wall space outside and suits homes where several rooms need cooling, with each room controlled separately.
Outdoor unit positions
Outdoor units are fitted on wall brackets, at ground level or on a flat roof, depending on the property and the pipe route. It needs space around it to breathe and for an engineer to work on it.
How it works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes about a day for a single-room system, longer for multi-room and ducted systems. Parking bays, permits and roof or balcony access are the first things we ask about in Rainham.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure someone can let us in at the agreed time
- Let us know where the consumer unit is

Advice
What happens if it’s left?
There’s a tax point for homes: installing energy-saving materials in residential accommodation is zero-rated until 31 March 2027, then 5%. Whether a particular system qualifies depends on the facts and we confirm the VAT on your quote. This is general information, not tax advice. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Rainham early.
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed price.
